| 摘 要： | 利用归纳法对Global Diagnosable Sequence的故障诊断能力进行了分析。分析结果表明：目前该算法＂关于征兆混淆问题＂的结论是不够准确的,除了满足一个基本互连诊断算法的抗混淆能力以外,还对W-A/W-O以及W-O/S-D-k无征兆混淆。并由证明过程得到以下结论：无W-O征兆误判的诊断算法必然不存在W-O/S-D-k征兆混淆。

| Abstract: | The fault diagnostic capability of Global Diagnosable Sequence is analyzed by means of induction. The resuhs indicate that the present conclusion about syndrome confounding is inadequately correct. The algorithm not only satisfies anti-confounding capability of a basic interconnect diagnosis algorithm, but also is confounding-free for W-A/W-O and W-O/S-D-k. Through the proving process, the authors draw a conclusion that W-O/S-D-k syndrome confounding can not exist in the diagnostic algorithm without W-O syndrome aliasing. |
